TSA on SLP offshore oil platform

A video showing Flame Spray TSA used on an offshore platform

Metallisation MK73 flame spray systems being used to apply thermal spray aluminium (TSA) to an offshore oil platform for corrosion prevention. The platform is destined for the North Sea. Long supplies packages (30m) were used to enable sprayers to move easily around the structure and increase productivity.

Flame spray TSA onto offshore oil platform with metallisation MK73 systems, the area of TSA was approximately 1,000 sqm to 250-400 microns.

The system allowed 30m of supplied from gas the flexibility to spray areas of 27m of long main column tubulars.

Aluminium coating specification

Blast to SA3, 70-100 Micron profile.
Thermal Spray Zn or Al to 100 Microns minimum Dft.
Epoxy Sealer, maximum 25 Microns Dft.
Primer and top coat to suit the final installation.

TSA (Thermal Sprayed Aluminium) for CUI

The video shows the preparation and application of Thermal Spray Aluminium (TSA) to protect pipelines and vessels against atmospheric corrosion and Corrosion Under Insulation (CUI).
This clip illustrates the complete process of applying Thermal Sprayed Aluminium to deliver effective corrosion protection or an (estimated) 20+ years.

After the Thermal Spray Aluminium has been applied, the blast profile is measured and saved to be used in an audit at a later date. Next, the site is inspected with a 10X illuminated magnifying glass to check if the blast surface is clean and to identify any embedded grit particles. After this, the area is tested using dust contamination tape by placing the tape onto the surface, removing and then inspecting with a 10X magnifier.

A salt contamination test is then carried out to inspect the presence of salt on the blasted area. This is achieved through the application of an agitate test solution, then using the test pipette to ascertain the level of salt.

Afterwards, check the bond strength and thickness meets specification.

TSA is applied by the flame spray process using a Metallisation MK73 system with long supplies package to assist in accessing hard to reach areas.

MK74-PC Powder flame

Metallisation MK74-PC, automated powder flame spray system.

The MK74-PC is a fully automatic powder flame spray system that can be robot mounted and interfaced with automation.

The video shows the simple operation in both manual and automatic mode, as well as an example of spraying an aero-engine component.

Met-Clad Laser Cladding

Metallisation MET CLAD Laser Cladding System

The video gives a brief introduction to the laser cladding process, shows a selection of laser clad applications.

The video also shows how easy it is to operate and control the laser cladding process with the Metallisation MET CLAD laser cladding control system. The Metallisation MET-CLAD laser cladding system takes control of all of the laser cladding process and simplifies it via a reliable and repeatable touch-screen control system.

LPG cylinder metal spraying

This video shows the automated zinc spraying of gas cylinders (LPG cylinders) with Metallisation ARC528E automated arc spray systems. This can be onto brand new cylinders or on reclaimed/repaired cylinders. The zinc coating is applied to give longer corrosion protection to cylinders compared to paints alone. The paint or powder coating are often damaged during manual handling and the zinc coating beneath provides a sacrificial coating.

Leading the Battle Against Rust

Examples of corrosion protection with both ARC and Flame Spray Systems on a variety of substrates.

HVOF Turnkey Installation at B&B Coatings Ltd

HVOF Turnkey Blast and Spray Installation at B&B Coatings

This video gives an overview of a turnkey blast and HVOF thermal spray installation, installed at B&B Coatings Ltd in Yorkshire, UK.

The project was the result of a co-operation between SciTeeX in Poland and Metallisation Ltd to supply a blast room, HVOF spray room, extraction, robot and MET-PCC(HVOF-L) liquid fuel HVOF system.

Historical steel production

This old video from the early 1970’s shows a number of metal arc sprayed coatings that were applied wit Metallisation systems in steel mills and foundries. These applications are still relevant and applied today. HVOF and laser cladding coatings have joined the arsenal of coatings used to combat the harsh environments of the steel mill. The film is showing its age but demonstrates that the metal spraying process is not at all new and has a long and proven history. Of particular interest is mention of the thick steel coatings (up to 50mm or 2″) applied in some applications.

Forth road bridge coating

The Forth Road Bridge (not to be confused with the Rail Bridge) was coated by Metallisation in the early 1960’s with zinc metal spray. This video shows some extracts from a longer video unearthed from the Metallisation archives.

A coating survey undertaken over the last couple of years showed very good levels of corrosion protection still in place, some 45 years + after the opening of the bridge in 1964.
